The United States, for its part, chose Embraer in February to provide the Air Force with 20 light attack planes - a deal many Brazilians saw as a necessary condition to buy the F-18.
Boeing has also deepened its partnership with Embraer in recent months.
Meanwhile, the government has been less happy with the other finalists. France’s recent agreement to build submarines with Brazil has resulted in fewer technology transfers than expected, one official said.
France and Sweden reportedly opposed Brazil’s candidate to lead the World Trade Organization, who won the post last month. The United States also favored a different candidate, but was more restrained in its support, in Brazil’s view.
“We notice these things, and they’re all factors in the (jets) decision,” a Brazilian official said. “This is so much money, and we want to choose the right partner.”
